 Here we use clusterDCA and clusterDCB as an example. We pick clusterDCA as the primary(used to called "master") cluster.
 The only difference of being a primary cluster is that it is responsible for domain registration. Primary can be changed later but it needs to be the same across all clusters.

+Then the domain should be failed over to clusterDCB. Now worklfows are read-only in clusterDCA. So your workers polling tasks from clusterDCA will become idle.
 
 Note 1: that even though clusterDCA is standy/read-only for this domain, it can be active for another domain. So being active/standy is per domain basis not per clusters. In other words, for example if you use XDC in case of DC failure of clusterDCA, you need to failover all domains from clusterDCA to clusterDCB.

 To build the :CLI: tool locally, clone the [Cadence server repo](https://github.com/uber/cadence), check out the version tag (e.g. `git checkout v0.21.3`) and run
